ProtonMail team does intend to release a cryptocoin in the future. It has come to our attention that others are trying to capitalize off of the Proton name to scam users at domain name protoncoin.io. This is a scam that is not affiliated with ProtonMail or Proton Technologies AG. The real ProtonCoin, when it is released, will live at protoncoin.com and twitter.com/protoncoin. Similarly, twitter.com/newprotoncoin is also a scam.
